CAR -COUPLING. 4

SPECIFICATION forming part of Letters Patent No. 309,702, dated December 23, 1884 Application filed August 19, 1884. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS .P. EVANS, a citizen of the United States, residing at Denver, in the county of Arapaho'e and State of Colorado, have invented certain newand useful Improvements in Automatic Car-Couplers; and I hereby declare the following to be a full, clear, and exact description of my invention, such as will enable others skilled in the art to which it appertains to make and use it, refer ence being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in I automatic car-coupling.

The object of my invention is to provide an automatic car-coupler, such that can be uncoupled without pushing the cars backward, and relieving the strain caused in the grip of the jaws. The jaw rotates on a pivot and held in position by means of a strong spring in a rigid frame. \Vhile the jaw is capable of free rotation around its axis, it is also held rigid in place by a strong sliding bar, which is operated by a spring-lever.

Myinvention consists of an automatic carcoupler actuated with a lever so that the spring and sliding bar can permit the jaw to rotate on its center or axis.

Similar letters refer to similar parts in the several views.

In the accompanying drawings, Figure 1 is a view in perspective. Fig. 2 is an enlarged view of thejaw. Fig. 3 is an elevation of the coupler in position. Fig. 4 is a plan of the coupler in position. Fig. 5 is a side viewof the jaw. Fig. (5 is a sectional view of jaw through R 1%,showing the method of support to the main frame. Fig. 7 is a view of the coupling-j aw detached.

A represents the jaw of coupler of suitable dimensions for the various heights of cars. 13 is the sliding bar,which is closelyfitted in the frame E, and connected with a' handle or wheel, F, by means of the small chain 1-. The pin N, which connects the spring S to the jaw, is fastened in the sliding bar 13, having a horizontal motion through the slot 0. The cover O is part of the drawhead and supports the handleF in the bearings a a. The small chain 9, which actuates the sliding bar B, passes through slot (1, and is wound around pulley P.

The ends It h ofspring S unite said spring to the pin N and jaw A. D is the space that the bar slides into when in operation.

It will be observed that when the two cars are connected as represented in Figs. 3 and 4, the spring S is in a normal state, and the sliding bar B projects out and behind the jaw A, so that when the pressure in pulling the cars comes against the faces of the jaws they become rigid. Further, it will be observed that in coupling the cars together the jaws will rotate around its pivot 12, and in so do ing expand the spring sufficiently far to allow the jaws to pass one another, after which the spring will immediately return them to the original position.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a car-coupler, the draw-bar E, having the springactuated jaw A pivoted thereto, said draw-head being provided with a sliding bar, B, and a casing, O, substantially as described, and for the purposes set forth.

2. In a ear-coupler, the combination of the draw-bar E, having slots De, the pivoted jaw A, bar B, pin N, and spring S, substantially as described, and for the purposes set forth.

3. In a car-coupler, the combination oft-he slotted draw-bar E, pivoted jaw A, bar B,having pin N, slotted casing (3, provided with wheel-rod F, a chain connecting said rod and bar B, and spring S, connecting the jaw and pin aforesaid, substantially as described, and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 13th day of August, A. D. 1881.
